5. Photosensitive drum cleaning block
In the transfer block, not all the toner is transferred to the paper. Some remains on the photo-
sensitive drum.
Also, the residual toner on the intermediate transfer belt is carried back to the photosensi-
tive drum by ITB cleaning.
The purpose of this block is to clean off the residual toner on the photosensitive drum so that
the next print image will be clear.
Step 9 Photosensitive drum cleaning
Prior to the next printing, the residual toner on the drum surface is scraped away by the clean-
ing blade to clean the drum surface. The removed toner is collected by the sweeper strip and
put into the waste toner container with the toner transfer plate.
